getMaxStackSize() for itemstack, player, and world objects

[Flamarow]

This function would be just how it sounds. It will output the max stack size for the item can be. That way you can have conditions like this:

if(itemstack.getMaxStackSize() < itemstack.getStackSize()) { //do something }

Main use for me would be to test if there is any room left in the player's inventory for a specific item, but I am sure this function could have other uses as well.

Added player.getItemMaxStackSize(), itemstack.getMaxStackSize() and world.getContainerSlotMaxStackSize().
